' souNn-nncoan CLEANER.

Specification of Letters Patent.

Application filed June 16, 1915. Serial No. 34,353.

. has forits object to provide an exceedingly simple and effective device of. this character which will resiliently hold a cleaning cloth or other suitable cleaning element upon the playing face of the sound record, so that the same will be wiped clean just previous to that part which is clean passing beneath the needle, the device being carried by the movable portion of the reproducing machine, whereby the cleaning cloth is carried over thesound record.

A further object of the invention is to provide an attachment for talking machines adapted to be fastened to some suitable portion thereof such as the sound box for the purpose of cleaning the sound records as the machine is played, thereby insuring a better tone to the music as well as prolonging the life of the record.

A still further ob'ect of the invention is to provide an attachment for talking machines, a portion of which is normally.

consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by. the claims.

Inorder that those skilled in the art to which this invention appertains may 1lIl-- derstand howto' make and use the same, I

will describe its construction in detail, re-

cleaner. Fig. 3, is a plan view thereof; and Fig. 4, is a front elevation thereof, a portion of the top plate being broken away.

In carrying out my invention as here embodied 2 represents a talking machine of any suitable and well known construction provided with a turn table 3 on which the sound record 4 is placed, and over which moves the sound conveying arm 5 having a sound box 6 attached thereto by meansof the rubber back 7 the latter being fastened by screws 8 to the sound box and to the sound conveying arm by the ordinary and well known bayonet slot and pin. g

9 denotes 'Iny improved sound record cleaner or attachment, comprising a top plate 10 having an opening 11 therein adacent each end and provided with an in- Patented Jan. 18, 1916.

tegral arm 12 projecting outwardly and up wardly from one edge thereof intermediate the ends, and this arm is twisted or formed with a spiral, so that the outer or free end thereofis at right angles to the inner end thereof, and said outer end is provided with a screw receiving opening 13, whereby the device is attached to some suitable portion of the talking, machine such as the sound box thereof by means of one of the screws 8 passing through the screw receiving opening 13 in the arm 12, the rubber back 7, and threaded into the sound box. A bottom plate 14 is attached to the upperplate 10 by means of posts 15 which pass through theopenings, 11 in the top plate and are slidably mounted therein, the ends of said posts being headed as at 16 to prevent their accidental withdrawal from the top plate.

' The bottom plate 14 lies parallel with the top plate, and is normally forced. away from the latter by spiral springs 17 coiled about the posts 15 and resting between the two plates. Thebottom plate 14 carries a pair of prongs 18 which are preferably formed integral with one edge thereof and project upwardly and outwardly, the upward projection of said prongs preventing the points thereof from coming in contact with the sound record.

A cleaning cloth 19 is secured to the bottom plate by means of the prongs .18, and when in use said cleaning cloth underlies the bottomplate 1'4 and rests upon the playing face of the sound record, so that as said sound record revolves beneath the cleaning cloth, the latter will wipe the record an take up, the. dust or other foreign matter on the record 'just previous to that portion being cleaned passing beneath the needle.

In practice the cleaning cloth 19 will be held in resilient or light contact with the playing face of the sound record by means of the springs 17 which normally force the bottom plate 14 carrying the cleaning cloth away from. the top platelO, which is held in a rigid position with relation to some suitable portion of the talking machine, such as thesound boxrby means of the arm 12, and the tension of said springs is only such as will hold the cleaning cloth 19 in light contact withthe playing face of the sound record, so'that the speed of the latter will not be diminished, and so: that said cleaning cloth will pulsate or move up and down with the irregularities of the record or the turn table on which said record is placed.

' When the talking machine is not being played or when it is desired to place a record upon the turn table, those parts which reprodu ce or convey the sound from the record are moved away from said record, and as the attachment is secured to some one of these movable parts, said attachment will also be moved away from the record or the turntable to permit the removal from or g the placing of a record on the turntable.

Of course I do not wish to be limited. to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims Without -departing fromthe spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is

1. A sound record cleaner comprising two parallel plates attached together and one of'which is movable with relation to the other, means carried by one of said plates for attaching the device to some suitable portion of the talking machine, and means carried by the other plate for attaching a cleaning cloth thereto.

2. A sound record cleaner con'iprising a plate provided with attaching means, an-

other plate provided with means for tastening a cleaning cloth thereto, and means for movahly attaching said second plate to the first named plate.

3. A sound record cleaner comprising a plate provided with attaching means, another platev provided with means for fastening a cleaning cloth thereto, means for movably attaching said second plate to the first named plate, and means for normally forcing' said last named plate. from the first named plate.

4. A sound record cleaner comprising .1

top plate having holes therein, attaching means carried thereby, a bottom plate provided with prongs, means carried by said bottom plate and slid'ably mounted in the holes in the top plate, and resilient means for forcing said bottom plate from the top plate.

5. A sound record cleaner comprising a top plate having holes therein, an attaching said plate intermediate its ends and pro-,

jecting outwardly and upwardly therefrom, said arm having a spiral thereln and provided with a screw receiving opening at its outer end a bottom late ron 's carried' 7 7 D thereby projecting outwardly and upwardly from one edge thereof, posts carried by said bottom plate and slidably mounted in the top plate, the ends of said posts being headed to prevent their accidental withdrawal from the top plate, and spring means for forcing the bottom plate from the top plate. o

7. A sound record cleaner comprising a top plate having holes therein, anattach- 'ing arm formed integral with one edge of said plate intermediate its ends and projecting outwardly and upwardly therefrom, said arm having a spiral therein and provided with a screw receiving opening at its outer end, a bottom plate, prongs carried thereby projecting outwardly and upwardly from one edge thereof, posts carried by said bottom plate and slidably mounted in the top plate, the ends of said posts being headed to prevent their accidental withdrawal from the top plate, and springs, one of which is coiled about each of the posts lying between the plates for normally forcing the bottom plate from the top plate.

In testimony whereof, I have hereunto affixed my signature in the subscribing witnesses.
